>Not much to mig.

Said by every retard who comes I to weld test at my job prior to employment and fails the overhead weld test after x ray, and often prior to an x ray because their shit is THAT bad.

They never even make it to Flux core or smaw/arc usually.

I don't even want to talk about the shit people talk about how they are 6G welders and certified and come in and throw errant weld jizz all over the fucking pipe coupon.

Trust me. It's easy to fuck mig up, get lack of fusion, porosity, etc...

>pic related is what most weld tests would look like when handed in if they were drawings that I've seen.

Another argument against building an expensive one first: You might not know what you want yet.
Do you want a 250mm one that can turn on a dime, a 350mm if you think you gotta go fast, or a 450mm one with a large battery and low KV motors for long range flying? You might realize that only after having invested a lot money.
